Detailed Description
The invention is further described in the following description and embodiments with reference to the drawings.
As shown in fig. 1 to 4, a voice coil motor with flexible feeding comprises a coil 1, a stator 3 and a coupler 2 which are coaxially arranged, wherein the coil 1 is inserted into the stator 3, the coil 1 and the stator 3 are both positioned in the coupler 2, the coil 1 and the stator 3 are respectively and fixedly connected with the coupler 2, and a spiral through groove 22 is formed in the side surface of the coupler 2, namely, a front through groove and a rear through groove are formed.
The coupler 2 is a cylinder with two open ends, and the through groove 22 is spirally arranged around the axis of the through groove.
The central shaft is a screw 35, the screw 35 is connected with a nut 34, and the paramagnetic steel 31 and the permanent magnet 32 are clamped between the screw 35 and the nut 34.
The number of the permanent magnets 32 is at least two, preferably three, the paramagnetic steel 31 and the permanent magnet 32 are in one-to-one correspondence and are alternately arranged, and the adjacent permanent magnets 32 are installed by adopting reverse magnetic poles.
The bottom of the side of the coupler 2 is provided with a stator locking through hole 23, the stator locking through hole 23 is arranged along the radial direction of the coupler 2, and a stator locking bolt for locking the outer cylinder 33 of the stator 3 is arranged on the stator locking through hole 23.
The coupler 2 is installed on the bottom plate, the outer cylinder 33 is preferably a copper cylinder, and the paramagnetic steel 31 and the copper cylinder are both made of low-carbon steel.
The coil 1 comprises a coil frame 11 and a coil 12, wherein the coil 12 is wound on the coil frame 11.
The coil 12 has at least two sections, and the adjacent coil 12 of each section adopts a reverse winding method.
The bobbin 11 is made of a diamagnetic material, such as an aluminum alloy.
The top of the side of the coupler 2 is provided with a coil locking through hole 21, the coil locking through hole 21 is arranged along the radial direction of the coupler 2, and a coil locking bolt for locking the coil framework 11 of the coil 1 is arranged on the coil locking through hole 21.
The voice coil motor with the flexible material supply can be used in a flexible vibration disc to carry out high-frequency reciprocating motion, so that a product is turned and shaken.
The motor load can be increased through three-section (multi-section) parallel connection, and high load is realized.
The current of the coil 12 in the motor is commutated at high frequency to achieve reciprocating motion, and high-frequency short-stroke reciprocating motion is achieved.
Every section of adjacent coil 12 adopts reverse winding method, and adjacent permanent magnet 32 adopts reverse magnetic level installation simultaneously, so design, coil skeleton 11 produces power with the magnetic field and carries out rectilinear motion under the electric current effect, after coil skeleton 11 moved the magnet edge, continue forward will enter into reverse magnetic field and form the counterforce, brake the effect to coil skeleton 11 (the load on the skeleton), this moment, electric current is carried out the reversal through control system in the coil 12, like this, coil skeleton 11 can the reverse motion.
